CAR-DOOR.

SPECIFICATION forming part of Letters Patent N o. 575,257, dated January 12, 189'?. Application led August 7, 1896. Serial No. 601,980. (No model.)

T0 @ZZ whom t may concern.:

Be it known that I, EDWARD S. MARSHALL,

a citizen of the United States, residing at the city of St. Louis, State offMissourL'have invented a certain new and useful Improvement in Oar-Doors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, wherein- Figure l is a side elevational view showing my improved car-door in a closed position. Fig. 2 is a vertical sectional view through the Eig. 3 is a vertical sectional view through one of the door-posts and door, the latter being shown open. Fig. 4 is a plan view of the track. Eig. 5 is a longitudinal sectional view through the door, showing the same in its closed position. Fig. 6 is a side elevational view of the roller-hanger which cooperates with thecrank-arm. Fig. 7 is an edge view of the same'. Fig. 8 is a detail view of the crank-arm which is mounted in the upper end of the operating-rod and which coperates with a stud on the bottoni of the rollerhanger. Fig. 9 is a side elevational view of the handle or hasp which is mounted on the lower end of the operating-rod. Fig. l0 is a top plan view of the same, showing the countersunk frame for the pivoted staple in section. Fig. ll is a plan View of the countersunk frame for the pivoted section. Fig. l2 is a detail view of the pivoted staple.

This invention relates to a new and useful improvement in car-doors, and more particularly to the mechanism for closing and locking the same.

The objects of this invention are to provide a car-door of that class known as Hushdoors which is simple in construction, easily operated, and readily locked to effectuallyprevent entrance to the car without breaking or mutilating the seal.

With these objects in view the invention consistsin mechanism which is mounted upon 'one end of the door, said mechanism being adapted to cooperate with that end of the door to throw the door into and'out of its flush position relative to the posts which form the side edges of the doorway. Incidental to this the track from which the door is suspended is so arranged that it guides the front end of the door into a flush position, permitting the rear end of the door to be swung into and out of a flush position.

Another feature of the invention resides in the construction of the handle on the lower end of the operating-rod, which handle acts in a capacity of ahasp, carrying its own locking-bolt and coperating with a pivoted staple, which, when the bolt is withdrawn and the hasp swung out to operate the rod and throw the rear end of the door out from its flush position, said staple will automatically fall to a position fiush with its support, out of the way of the passage of the door.

Another feature of the invention resides in the provision of truss-rods for the door-posts, whereby said posts are strengthened against being bulgedout in the middle, which would prevent the door from moving freely.

Another feature of the invention resides in the construction of the guide at the lower left-hand corner of the door and the manner of securing the same to a car, rendering its removal impossible when the door is closed or locked.

Other features of the invention reside in the construction, arrangement, and combination of the several parts, all as will be hereinater described and afterward pointed out in the claims.

In the drawings, A indicates the side wall of the car, B the side sill, C the floor, and D the door, all of such parts being of any ordinary or approved construction.

E indicates posts at the side edges of the door, which posts are grooved on their outer faces to receive a truss-rod E', which extends through the sill at the bottom of the car and through the facia at the top of the car. lVhen the car is heavily loaded, the tendency of the side walls of the car is to bulge outwardly, which would tend to bind the door and prevent its easy operation. By the presence of these truss-rods in the door-posts, by tightening the nut on the lower ends of said rods said posts may be readily straightened from their bulged position and cambered inwardly, if desired.

F indicates the track f or the door-hangers, which is arranged near the top and on the outside of the side wall of the car. This IOO track preferably consists of a fillet of wood, to which the strap-iron forming the track proper is secured. This construction, however, is unimportant, as other forms of track could as satisfactorily be used in connection with my improvements. This track recedes at its end toward the side wall of the car, so as to guide the front and back ends of the door inwardly when the door is moved to its two positions. Incidental to this the crown or bulged portion of the track guides the door outside of the post, which the door passes in the opening and closing operation.

G indicates the slide-hanger, secured to the upper front end of the door, and which cooperates with the track F.

l-I indicates a roller-hanger which cooperates with the track F, said hanger being provided with a stud or projection 7L on its lower end for engagement by a crank-arm I, mounted on the upper end of an operating-rod J, journaled in suitable bearings j, secured to the car-door. This crank-arm is preferably formed with an opening or slot for receiving the stud 7L, which stud is preferably formed with a head on its lower end, and after the stud is in position in the slot the end is closed by a pin t, which is secured to the jaws forining the slot. This crank-arm is, iixed to the upper end of the operating-rod.

By the above construction it will be noted that a half-revolution being imparted to the crank-arm will throw the car-door inwardly or outwardly the distance of the diameter of the arc described by the open end of the slot in said block.

K indicates a handle mounted on the lower end of the operating-rod, said handle being in the form of a hasp which is adapted to cooperate with a pivoted staple L, mounted in a frame M, countersunk in the door-post, so that when said staple is not in an operative position it will fall by its own gravity to within the lines of the post.

N indicates a bolt pivotally and slidingly mounted on a stud Z, extending from an extension of the handle K. This bolt is slotted to receive the stud, and the lower end of said bolt is also formed with an opening for the passage of the seal-wire, whereby the door may be sealed when locked.

O indicates a guide for the front lower end of the door, said guide being provided with an inward extension o, which is adapted to be secured by a wood screw to the sill.. By

this manner of securing guide O the saine is practically burglar-proof, because itis impossible to removethe same unless the door is opened and the sill-plate taken out.

P indicates a guide at the rear end of the door, said guide being of such width as to permit the rear end of the door to swing outwardly a sui'icient distance to clear the post, as shown by the dotted lines in Fig. 5.

In operation when the door is closed the upper front end is guided inwardly by the slidehanger cooperating with the receding portion of the track, and the lower front end of the door is secured in place by passing inside of the guide O. The handle K is now turned, we will say, from left to right, which forces the upper rear end of the door inwardly, so that the door is between the two posts and flush with the same. The pivoted staple is now raised so as to pass through the opening in the free end of the handle, and when the pivoted and sliding bolt is inserted through the opening in' the staple the lower rear end of the door is locked in position. A seal may now be applied to this bolt, as is common.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted ior those herein shown and described without in the least departing from the nat-ure and principle of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. The combination with a car-door, of a post forming the edge of the doorway, and with which the door is adapted to cooperate, said door being also capable ot clearing the post in its movement to and from the doorway, said post being grooved on its outer face, and atruss-rod seated in said groove and having its ends passing through timbers above and below the post; substantially as described.
